gayaneshka [121]

Number 2 is incorrect :

\frac{-25x^{3}+15x }{5x}  = \frac{-25x^{3}}{5x} + \frac{15x}{5x} = -5x^{2} + 3

Number 1 :

(-5)^{3} . 13^{-2} . (-5) .13^{9} = -125 . \frac{1}{13^{2}} .(-5).13^{9}   = 625 . \frac{13^{9}}{13^{2}} = 625 . 13^{7} (i dont think we can bare calculate this cause it;s too big ;-;)
